Surfacing machinesof the above vtype include a rotating cutter head andgrippingV members -movable toward and away from the headV fon passingthebillets therethrough. rThe cutter headA is mounted ina suitablecasing'and has rotation therein about the axis of the billet -to perform itscuttingaction. Adjustably secured to a carrying ring are a ,pluralityfofcuttingtoolsV and in order for the machines tovaccurately resurface thebillets it is essential that the toolsbe set at exactly the samedistance--fromthe cutting center. y *Y An'object of the presentinvention visto provide a .gauge that can be readily 4applied with- .outremoving the heavy carrying ring from the machine and which will enablelthe operator to` .'ly set tools withv precision and which will-be simple4Vin construction and fulfill all requirements vof service andmanufacture. Y

With these vand various othenobjects in View, the invention may consistof certain novel features of construction and operation as willfbe morefully described and particularlypointed out in the specication, drawingand claims appended hereto.

includedfasfpart of the cutting mechanism is an adjusting ring ,I4vpositioned concentric `with V the arcuate membersllfand receivingthreaded adjusting bolts I5 which are locked in position the ringbythelock nut I6. A` groove I1 isv vprovided in the face `of*theladjusting` ring for vpurposes which will be -presently"described,thegroove connecting a plurality of spacedV threaded fre'cesses I8- Vlocated adjacent VAeach adjusting bolt I5v."r` 'j A '1` j i The toolsetting gaugebymeans of which the cutting tools I3'lcanlbe` accuratelypositioned` Ain `the tool carrying member incldes`anfarm` having securedto fits vertical iacel the 'wearplate 2| and receiving anadjustmentblock 22 which by means'of the `bearing"plate 23 and setadjacent one. of` the graduations 25, depending 'on the'particular siteof billet tov be resurfaced. Secured Yto one face of `the adjustmentblock `is a` guideplate l for receiving Va portion "of the indicatingmember-pivoted to one end of the `bloclr bythe screw 2'I'and including'ahead portion 28 and an indicating4 arrow 3l).tz By'. means of thecoilspring 3|, which has engagement with oneend of theiiug 32vprovided`on`the arrow 30 yand at its other end with set screw 33, the irldicatingvarrow is resiliently urged in 1a.downthe tools I3.

Wear-plate 2I,'secured to the face of thejarm 20 yscrew 24'may belockedin Vpositionon the' arm `3'0y 'ward directionin order to maintainengagement y between the". head 28 andthe cutting edge of,

As rmore particularly lshown in Figure 3` the v by screws 34, isprovided with an arcuate `rib Y adaptedv to have Vinteriitti'ngengagement with the groove I1 formed inthe face of the adjust- Y ingring. Extending through bore 35 is a locking screw 36 threadedjat oneend andhavingv pivotally secured tothe other end a handle 31, thethreaded end being adapted for threaded engagement with the recesses `I8wherebyy the gauge arm-'is rigidly' secured to the adjusting ring withcorrect positioning of the larm being assured by the interflttingengagement of the ribl formed formed on the wear-plate and the groove inthe adjusting ring.

In operation of the 'cutting mechanism l,the cutting tools soon wear,*requiringV frequent re grindingY and resharpening. Each tool may beremoved from the mechanism without4A disturbing the setting of the othertools by merely loosening the bolts I2 and Vremoving thektool-throughthe cutting opening. It is `desirable when removal of any of the partsof the cutting Vmechanism. VThe arm 20 is secured to theY adjusting ring'I4 bythe locking screw '36'adjacent the particular cutting tool whichhas been replaced.

The adjusting-bolt .I is first loosened androtated outwardly of thecasing so as to allow insertion and positioning of the 'cutting tooloutwardly of the circle defined by their inner sharpened edges and theadjustment block v22V lis positioned on the arm atV the'particulargraduation for the size billet being resurfaced. 'The resilient means 3|forces the indicating .arrow downwardly and the head 28 upwardly intoengagement with the cutting tool and Linofrder 'to rcorrectlypositionthe latter fit is onlygnecessary to :rotate the bolt I5 in thatdirection vto force the cutting tool downwardly which effects rotationof thefindicating member.
